基于层次分析法的库岸高速滑坡危险度评价

AHP-based hazard degree assessment of high-speed landslide of reservoir bank

高速滑坡的判定是滑坡治理工作中的一项重要内容,但由于目前尚没有统一规范的滑速计算方法,因而给高速滑坡的预测带来了一定的困难。层次分析法是一种定性与定量相结合的多目标决策分析方法,针对库岸高速滑坡发生的各影响因子,采用层次分析法对鹅公带古滑坡体的高速滑坡体危险度进行了分析评价,为库岸高速滑坡的预测提供了一条新思路。

The jubgement of highspeed landslide is an important content in the landslide control work;however, it brings certain difficulties of highspeed landslide prediction due to the unavailability of normative approaches of slid- ing speed calculation at present. AHP （analytic hierarchy process） is a multi -objective decision analysis method through the combination of qualitative and quantitative analysis. This paper aims at various influencing factors of highspeed landslide taken plance on reservoir bank, uses AHP to analyze and evaluate the highspeed landslide haz- ard degree of the Egongdai ancient landslide, and provides a new thinking on the reservoir bank highspeed landslide prediction.
